We have all seen the black and white films: Cary Grant is walking along a rain-swept London street and sees a cab in the distance, he whistles, and the vehicle practices an impressive u-turn. But how does this transcend real life? A question posed by Taxi Point found the whistle divides opinion. The whistle is still heavily used by the hotel doorman to call up the next taxi when the rank is set back from the entrance. This act has been used for decades and even dates back to horse and carriage times. TaxiPoint asked its readers whether it was rude for a customer to whistle at them when trying to hail a taxi. Some were quite happy with bringing whistled, however, the main argument for cabbies was that they didn’t like the action as it was the link to a submissive command usually aimed at dogs.
